INK-FOUNTAIN FOR PLATEN PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 384,216, dated June 5,1888.

Application filed Octobcr 2-l, 1887.

Serial No.253,273. (NomodeLl To all whom it may concern.-

Be it known that I, WILLIAM H. Peron, Jr., of Cleveland, in the countyof Cuyahoga and State of Ohio, have invented certain new and 5 usefulImprovements in Ink Fountains for Platen Printing-Presses; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit pertains to make and use the same.

My invention relates to improvements in ink-fountains forplatenprinting-presses; and it consists in certain features of constructionand in combination of parts hereinafter described, and pointed outin'the claims.

In the accompanying drawings, Figure 1 is a View in perspective showingthe iukfountaiu in position on a portion of a press. Fig. 2 is a frontside elevation of the ink-fountain. Fig.

3 is a rear side elevation of same. Fig. 4 is a bottom plan of the pawl.Fig. 5is a detail of the lever and pawl, showing the latter in itsreversed position. Fig.6 is a rear side elevation of the clamp, showingalso an arm of the 2 roller-frame in section; and Fig. 7 is aview inside elevation of the pawl-lever and ratchetwheel, the pawl beingdisengaged from the ratchet-whee].

A represents the body of the fountain, the

0 same having a sloping bottom, I3, sides C, and

' housings D, all cast integral.

E is the feed-roll, the trunnions e of which operate in the housings,with half boxes d above the trunnions, and thumb-screws d, fordepressing the boxes, and thereby holding the roller as near the frontedge of bottom B as may be necessaryto give the desireddischargeof ink,more or less, according to the amount of typesurface used in the formthat is to be inked. The feed-roller E, although it fills the spacebetween the housings, is preferably only about three inches (more orless) in length, for the reason that such short roller may be raised farenough to supply any amount of ink that may be wanted, and in case avery small quantity of ink is required-as would be the case, forinstance, in printing small cards-such small supply can be betterregulated with a short roll than with a long roll. 50 a feed-rollertwelve inches long, when set as It is evident that close to the bottomas may be and discharge ink at all, will discharge four times as muchink as a roller three inches long under the same conditions. On one ofthe trunnions of the feed-roll is mounted and keyed fast theratchet-wheel F, the latter being actuated by a gravity push-pawl, G.

H is a lever of the bell'crank variety, this lever being pivoted at h tothe side of the fountain. Pawl G is pivoted at h to the short dependingarm of this lever. Link I, at i, is pivoted to lever H. This link isalso pivoted to clamp J, the latter being secured to the one arm ofroller-frame K. The stud j, that fastens the clamp to frame K, servesalso as pivotal connection for link I. The pawl is offset on the sidethereof next lever H, forming a shoulder, g. This shoulder, by engagingthe lever, serves as a stop for the pawl when the latter is turned ineither direction. (See Fig. 5 and dotted lines, Fig. 2.) To render thefountain inoperative, the pawl is reversed, and by means of shoulder gaforesaid the pawl remains approximately in a horizontal position.(Shown in dotted lines, Fig. 5.) For operating the fountain, the pawlusually should move the ratchet-wheel only one or two notches at eachstroke of the machine; but clamp J is necessarily so far removed fromthe axis of frame K that the sweep of lever H is likely to be enough toactuate the pawl a distance of several notches. To remedy thisdifficulty, shoulder g is made to engage the short arm of the lever Hwhen the long arm of this lever is about midway of its upstroke, byreason of which the pawl is kept from engaging the ratchetwvheel untilabout midway of the downstroke of the lever, (see dotted lines, Fig. 2,)and when such engagement occurs the engaging end of the pawl is aboutunder the axis of the ratchet-wheel, in consequence of which thepressure of the pawl on the ratchet-wheel in turning the latter isforward and upward and tends to hold the feed-roller up against itsboxes rather than to depress the roller. 5 While the pawl is drawn backthe consistency of the ink is usually such as in a measure to buoy upthe feed-roll.

With some of the devices in ordinary use it has been customary tofulcrum the pawl-lever 10o lower rib, 7c.

on one of the trunnions of the feed-roll with a hook-pawl pivoted to thelever and drawing rearward and downward on the ratchet-wheel inactuating the latter, by reason of which the inking-roller was likely tobe depressed by the action of the pawl, causing an irregular feed, andsometimes shutting oil the ink-supply altogether. Of course springscould be arranged to support the feed-roller as against such down wardaction of the pawl; but this would require modifications in the generalconstruction, and would considerably increase the cost of the fountain,while my purpose. is to make a first-class fountain at a minimum cost.

The arm K, to which clamp J is attached, is usually approximately of theform shown in Fig. 6. I-Ieretofore the hook end of the clamp was made toengage the upper rib, is, and the set serewj, if set opposite this rib,would be so near the upper edge of arm K that it would likely slip off,and if the set-screw were placed farther down a line from the point ofthe set-screw to the point of the hook end of the clamp would be obliqueto the rear face of arm K, and consequently in such case the tendency ofthe set-screw would be to move to a point opposite the hook end, and indoing so would become loosened. I make the hook end J of the clamp longenough to reach past the front side of arm K and hook under the Withsuch construction, when the set-screw is applied, for instance, midwayof the rear face of arm K, or even farther down, the tightening of theset-screw draws the body of the clamp against the upper edge of arm Kand draws the hook end of the clamp up attachments, substantially asindicated, of

clamp J and link L, for actuating the fountain from the movement of theinkingroller frame, said clamp being adapted to embracethreesidesofsuchinking-roller frame,and asetscrew for fastening theclamp, such setserew serving also as a pivotal connection for the link,substantially as set forth.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 4th day of October, 1887.
